Adjusting the battery voltage via the LCS tool
NOTE For authoritative instructions on the LCS tool, please consult the applicable product documentation.
1
Enter your SMA Grid Guard Code in the “Service” > “Grid Guard” tab. If you do not have the code, please
contact our service center.
2
Access the active power input field in the “Inverter Parameters” > “Support Settings” > “Immediate controls” >
“Active power [P_Ref]” tab and set active power to 0 % > Put the STPS on standby and save the settings
(“Save”).
3
Access the active power input field in the “Inverter Parameters” > “Support Settings” > “Immediate controls” >
“Active power [P_Ref]” tab and set active power to 0 % > Put the STPS on standby and save the settings
(“Save”).
4
Set the following parameters under the “Power Management” tab:
Limited Export enabled “Off” | Peak Load Shaving “Off” | Time of Use “Off.”
5
Determine the ACTUAL DC voltage using the APU or STPS display or the LCS tool and compare this with the
TARGET voltage of 700.0 V
DC
(14 battery modules with 50.0 V
DC
each).
Note: The stored energy must be prevented from being fed back into the utility grid. The energy fed in from the
battery storage system must therefore not exceed the current consumption in the local utility grid.
6 If you have to reduce the voltage of (discharge) the STORAGE-67-TS-10, enter a value between 0 and 100 %
[positive number] for
“Active Power [P_Ref].”
7
If you have to increase the voltage of (charge) the STORAGE-67-TS-10, enter a value between 0 and -100 %
[negative number] for
“Active Power [P_Ref].”
8
Monitor charging or discharging to the target voltage of 700.0 V
DC
.
9
When the target voltage is reached, slowly reduce the charging/discharging power to 0 %.
10
Compare the voltage of one of the existing modules in the storage system with the module voltage of the expan-
sion modules. Both values must be 50.0 +/-0.1 V
DC
.
11 Adjust the voltage of the storage system until the new and original modules are at the same voltage.
10.2 Capacity expansion using additional STORAGE-67-TS-10 units
ATTENTION! Risk of damage to the unit and/or battery inverter if the unit is expanded by differ-
ent capacities.
If you wish to use multiple STORAGE-67-TS-10 battery storage systems with one STPS 60-10, it is imperative that
they all have the same capacity.
NOTE Up to four STORAGE-67-TS-10s per STPS 60-10 may be connected in parallel following the master/
slave principle.
NOTE When adding a slave, a BatBreaker must also be ordered and installed.
